Hi Coco..
I'm a little bit skeptical of the V2 armor in practice. Nude has not fully explained it. There is a lot of conjecture on Reddit about how it works, that there is argon pressurized in the bottle that helps push out the nic, and then I assume once the pressure is stabilized, the bottle will allow some vacuum before air gets in. Again, all a guess. You would think to make their claims, they would substantiate them with a more detailed description. Personally, I see air getting in after some draws, if not immediately.
I also was very unhappy with their CS. Took quite a bit of time to get mine. When it showed up, there were NO luer lock syringes as advertised. I wrote them, had to take a picture and send it to them, of the packing slip so they knew who prepared the shipment. Wouldn't it be a good idea to log that info internally, and NOT burden your customers with it? In addition to the 10 or so days it took to get the nic, it took about 3 additional weeks to get the syringes. So if I NEEDED the nic, it would have been a month from the time I ordered. They didn't seem surprised, apologetic, nothing.
Here are current prices with shipping of 100mg nic:
Nude V2 500ml $75.45
MFS 500ml in glass $55.69
MFS 1L in plastic $56.00 1L is the smallest plastic bottle they have
Nic River 500ml plastic $43.00
Also, the MFS 100mg comes in 125ml glass for $18. So you could actually purchase 4 125's in sealed glass for about the same price as the Nude V2, and not have to worry about whether or not ..... V2 "armor" really works. My MFS was 3 years old, almost to the day, when I opened it, and it was perfect. Nude claims "up to a year" for their shelf life. Based on my experience, I'd take 4 convenient 125ml bottles that I can count on for 3 years, over 1 500ml bottle that I can't be sure of.
You might even think about calling MFS, and letting them know you want 500ml, but you want it in 4 seperate, sealed glass bottles. They might work a deal.
Edit: Also, my MFS was 100% PG, which at that time, was thought to maybe have a longer shelf life than VG. It seems that thinking has changed now. That VG lasts longer. I dunno. But on the PLUS side of VG, it is like MOLASSES out of the freezer. If you knocked it over, you would have to WAIT to spill it.
